b43: bcm4318 can't create ibss or set channel
I keep getting a "Invalid argument (-22)" error whenever I try to create an
IBSS adhoc network or whenever I try to change the channel or frequency. "iw
reg get" also gives me weird values, I think -- eg. lots of "N/As".
My card is BCM4318 (14e4:4318 (rev 02)). I'm using the latest working firmware
for my wifi card (666.2, 2011-02-23), and the latest kernel (4.19.2). Thoughts?

Even when I try to use the old iwconfig, I can't connect to an IBSS network
with a slightly different error message, repeated over and over again:
# iwconfig wlan0 essid blabla
wlan0: Selected IBSS BSSID 52:fc:75:5d:a0:d4 based on configured SSID
wlan0: Failed to join IBSS, beacons forbidden
